Combat:
Centurions attack with two weapons (usually short spears, maces, and daggers) in the same round without any penalties for doing so.  Along with weapon attacks, they can attack with a bite attack as well.  Centurions are not agressives unless they are confronted with artificial light, their homes or nests are molested, or are on a foraging march.  If any of those instances are met, they attack instantly and relentlessly until the threat is driven off.

Society:
See the Alien Compendium 1 for more information.

Characters:
Centurions have not been proven to be fully sentient, so they cannot be used as a PC race.
